The Turbocharger That Rescued the Diesel Engine

Discover the engineering marvel that saved the diesel engine from extinction by turning wasted exhaust into raw power. In this video, we explore the history and mechanics of the turbocharger—from Alfred Büchi’s 1905 breakthrough to the high-performance engines produced by Cummins and Caterpillar today. You’ll learn how these devices spin at 100,000 RPM to recover one-third of wasted energy, effectively boosting efficiency by 50% and changing the automotive world forever.
